SPECIFICATION forming part of Letters Patent No. 474,614, dated May 10, 1892.

Application filed April 14, 1890. Serial No. 347,866- (No model.)

To all whom it may concern:

Beit known that I, JOSEPH A. TREAT, a citizen of the United States, residing at Stuart, in

- the county of Guthrie and State of Iowa, have invented-certain new and useful Improvements in Cash-Registers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in cash-registers; and the invention relates tol that class of registers in which there is a series of keys operating a series of tablet-rods, a registering mechanism, and a recording mechanism for recording the individual sales, as well as registering the total amount thereof.

The invention consists in the improved construction, arrangement, and combination of the various parts, and more especially as to the following particulars: First, the arrangement of the keys in a single bank or group of ten when using the decimal system, comprising a cipher-key and nine numerals, and in the construction of the keys andl indicating mechanism, whereby the indication of th'e amount is not commenced until the registration is completed or nearly completed, and in the mechanism for preventing the simultaneous operation of two or more keys upon the tablet-rods; second, the construction and arrangement of the connection between the keys and the tablet-rods, whereby a'single strikerarm is moved to operate any desired tabletrod; third, the construct-ion of the registering mechanism, whereby the total is always indicated by reading the numbers exposed upon the adjacent wheels and whereby the registering-wheel of any denomination may be operated independently of any other, all of saidy removed.

Figs. Sand 9 are diagrams showing the operation of the hood and connecting mechanism. Fig. 10 is a diagram perspective showing the shifting tablet-arm and its operating mechan-y ism. Fig. 11 is an elevation, partly in section, of the registering mechanism. Fig. 12 is a cross-section thereof on line x in Fig. 11. Fig. 13 is a similar cross-section showing a different. point of operation. gram plan 0f the mechanism for preventing the simultaneous operation of two or more keys. Fig. l5 is an end elevation, and Fig. 16

is a front elevation of the same.

Fig. 14 is a dial is the frame of the machine, supporting the operating parts.

2 are the operating-keys, consisting, when used in the decimal system, of a single group of ten. 3, upon whichis placed a number. These keys are numbered from l to 9, inclusive, the lefthand key being No. l. a cipher-key and is arranged at the right of the machine. This arrangement is'not essential, and any otherV arrangement may be made.

5 is a shaft upon which all the keys are journaled. Each key is `held in its normal unoperated position by a spring 6, connected at its lower end to the key, and at its' upper end to the bar 7, as shown in Figs. 2 and '3.

The tenth key 4t isl Each key has a suitable finger-piece Below the keys is slidingly secured the barS,

which on :its upper side is'provided withthe arms 9, one under each key.

A are standards carrying the projections B, engaging in the slots C of the bar 8 and forming the support and guide therefor. The arms 9 have an incline 10, extending nearly their whole length, and the vertical portion l1.r Vhile the key is vbeing depressed, it rests upon the incline, thereby moving'the bar 8 to IOO the left until the key reaches the vertical porlever 13, which is connected at its end bythe i bar 14, the whole making a rectangular' frame, secured upon the shaft 15, which is pivotally supported in bearings secured to Vthe frame.

The bar 14 is arranged immediately in front of the tablet-rods 16, which are arranged in groups of ten from front toback, each group representing a denomination.

In the'drawings I have shown tive groups, representing cents, dimes, dollars, tens, and hundreds, arranged from left to r-ight, respectively,the customer reading the nu m-bers upon th-e back of the tablets. The front rod 17 of each group bears a tablet marked zero, the remaining'rods bearing tablets marked, 1respectively, from 1 to v9 from fron-t to rear.

18 is a sleeve slid-ingly secured upon .fthe rod 19, secured transversely to the mac-hi ne immediately'behind the'bar-S and carrying ait-'its rear side the tablet-operating rod 20, pivoted thereto, preferably of the shape shown-that is, consisting o-f the bif'urcated frame a., forming a brace against `lateral strain, to the end of which is secured the rod b, upon which is slidingly secured the hollow sleeve c. To this sleeve -c is secured the plate d, which forms a broad bearing upon the bar 14, and which carries the upwardly-projecting tablet-lifting arm e, adapt-ed to vengage with theinVerted-V-shaped bearing )ifo-ruled' on the bottom of the tablet-rods, as hereinafter described. The hollow sleeve chas formed upon it centrally the'guide groove or bearing .g,vwhich sl-idingly engages with the bar 21,

which is connected bythe arms 22 with the swinginghangers 23, pivoted to the top of the machine, oneon each side of the key-levers.

i The hangers have the, Icurved portion 24,

with `the slot 29, in which is adjustahly secured'in any suitable manner the pin 30, arranged in the path ofthe key-levers. These rock-arms are arrangedat a gradually-increasyingdistance from the key-levers from right to left, so placed that the shaft will be rocked through the greatest are of a circle by the 9 key and through the least arc bythe Il fkey, correspondingly moving the `segment 3l, secured at the left end-of the shaft 26 upon the arms-32 and engaging'with the gear-wheel 33 of the registeringmechanism, A 1

consisting of a train of coactiug registeringwheels 34 upon the shaft 35 at the top of the machine, and upon which the gear-wheel y33 isV loosely journaled. The segment is normally held in its initial position by means of the spring 36. (Shown in Fig. 2.)

The registering mechanism w11l be more fully hereinafter described. The sleeve 18,l

carrying the sliding extensible tablet-operat ing arm 2O is operatively connected to the bar 8 by means vof the spring-pawl 37, engaging Wit-.hthe ratchet-bar formed on or secured to the rear yside of the bar 8, Fig. 10. The sleeve` 1S is also providedwith a spring-pawl 39, en.- gaging with the stationary ratchet-bar 40, secured -parallel to the bar 8. Each of these pawls have portions extending partially over the space between the stationaryan-d movable ratchet-bars, adapted to be struck by the swinging bar 41, extending beneath such portions of the pawls and supported by the links 42. Said swinging bar is adapted to be raised -to disengage the pawls si multaneously by the vcam or 'lug`43, Fig. 7, upon the rod 44, which is slidingly secured at the right of the machine, for-the purpose more fully herein-after explained. As the key descends, riding upon the incline 10 of the arm 9, it carries the bar 8 vto the left. The pawl 37 is raised by the ratchet 38 upon the bar 8, moving beneath it one notch. As soon as the key is released, the spring 134 draws the harS to the right, which *through the ratchet-bar 38 and the pawl 37 moves with it the sleeve 18, which is held iln its adjusted position by the engagement ot the pawl 39 with the stationary ratchet-bar 40.

45, Figs. 2 and 14, are a series of horizontal tu mblers pivoted at their forward ends tothe case of the machine, having a bearing upon the cross-bar 7 centrally and extending with their rear ends in proximity to the Wards 47 secured upon the upper end Vot' the Ilexible arms 4S, one connected to each ot' the key-levers. Upon the right of these tu mblers'is a-fixed-stop 46, preventing their movementin that direction, while the tumbler 49 upon the extreme left yis connected by meansof a double crankshaft 50 (see Fig. 14) with the sliding lock- IOO IIO

ing-bar 51, which extends under the keys, and I fis provided with the slots 52,` all -so'arranged that upon the operation of a key the ward 47 IZO the lever 13 rises and the bar is returned likewise bythe tension of the spring ,Should the operator attempt to operate-another key before the return of the operated vlO key, but after the lever 13 has left the slotthe lever 13 engages in the slot 52, it is evi-v dent that the second key could be depressed only partially', as any further movement of the bar 51 would be prevented by the engagement of the lever 13 in the slot 52.

The tablet-rods are arranged in suitable guides 55 56 and carry suitable indicatingtablets, as before described. These tabletrods are spaced a little distance apart at the bottom, but are inclined, as shown in Fig. 2, so that-the tablets are close together, so that there is the least possible space between them. Each group of tablet-rods is separated a slight distance from the other. The tabletrods of each group are provided with a foot or flange 58 to prevent accidental displacement should the machine be inverted and with a shoulder or detent 59, with which a spring-pawl 60, common to all the rods of each group, engages in the elevated position of the rod, as shown at the left hand of Fig. 6, said pawl passing across all of the tablets of its group, so that when one tablet of said group is dropped all of the tablets in that group which may be up are likewise dropped.

6l is a latch held normally in a horizontal position by a stop 62, but free to move upward. As the tablet rises the latch 61 strikes the pawl 60, throwing it out of engagement with any previously-operated tablet-rods and allowing them to drop. In the downward descent of such rods the latch swings upwardly, offering no obstacle to the movement of the rod.

135 is a tripping-bar having shoulders 63 eXtending'into the path of the pawls 60. This bar is actuated from the rod 64, which is slidingly secured beside the tablet-rods in vertical guides and carries the latch 65, engaging in the downward movement of the rod with the top of the incline-plate 66, secured upon the end of the rod 135, tipping the latch backward; butin the upward movement of the rod the latch engages with the incline and moves the bar 135, disengaging the pawls from all of the tablet-rods, the latch passing on and above the inclined plane, and as soon as released the bar is returned to its normal position by the spring 67.

44, Fig. 5, is the setting-bar, extending through the front of the machine and provided with a suitable handle 69. This bar is held in position by the spring 70. The purpose ofthis bar is to set the parts in position ready for each operation and to operate the hood or slide for covering and uncovering the operated tablet. Said bar carries the lugs 43 and 122, which operate, as before described, to move the lifting-bar 4l, Figs. 4 and 5, and also the lifting-bar 123. It also has upon it the inclined lug 71 at or near the rear end, upon which is supported one end of the lever 72, Figs. 5 and 6, which at the other end supports the vertically reciprocating bar 64,

Awhich at the upper end connects with the curtain-supporting lever 74,'Fig. 8, pivoted in the tablet-chamber 75, formed upon the top of the machine. This lever 74 carries at its rear end the curtain or slide 76, which closes and discloses the aperture 77 opposite the elevated tablets toward the customer. A friction 'spring or brake 78 holds the bar in its adjusted position.

79 is an arm on the bar 64, projecting over the cross-bar 14 of the tablet-operating lever, so arranged that the upward movement of said lever will strike the arm 79 and carry with it the vertically-reciprocatingbar64, Fig. 7, thereby lowering the hood or curtain to obscure from the purchaser the indication of the amount of his purchase. f

After the operator'has indicated the proper amount by means of the mechanism previously described throwing up the proper tablets he pushes in the lever 44, which carries the inclined lug 71, which acts through the medium ot the lever 72, connected to the bar 64, to raise the curtain and expose to the viewof the purchaser the amount indicated.

My recording mechanism is of the following construction: 80 is a segmental figureplate having an extended hub or collar 81, slidingly secured upon the shaft 26 by means of a suitable feather and feather-way. This plate, Fig.' 5, is provided with a series of figures upon a segmental circular face 82. These figures correspond to the figures upon the keys--that is, consists of a cipher and A nine n u merals.` Y

83 is a vertical lever pivoted atits lower end to the bracket 84 and provided with a pin 85, slidingly engaging with the annulaigroove 86, Fig.5, in the collar 81. 1 This groove is shown in dotted lines in Fig. 1. The lever 83 extends upward beyond the pin 85 and at its upper end isvprovided with the slot 136, engaging with the pin upon the sliding sleeve 88 upon the shaft 35, Fig. 4, carrying the registering mechanism, the operation ot' which will be described hereinafter.

89 is a recording-lever pivoted in suitable bearings 90 upon the base of the machine and extending upwardly and rearwardly, its rear end being provided with the hammer or head IOO IZO

91, arranged opposite the face of the segmenv tal circular plate 82, Figs. 5 and 7. This lever 89 is provided with an arm 92, which rests upon the tablet-actuating lever 13 near the rear end thereof. y f

93 is the ink-carrying ribbon, (shown in dotted lines in lig. 5,) which at its upper end is wound upon the spool 94 and at its lower end 4 l I v474,614.

v Vupon the spool 95,.and is guided across the face of the plate 80 by the circular guide 96,

which opposite the hammer is provided with 1 'a suitable aperture to allow the blow of the hammer t strike the ribbon against the type.

97 is a strip of paper wound at its upper end upon the roll 98 and at its lower end upon f the roll 99, being guided across vthe face of the plate 80 bythe guide 100, a suitable interme- IOI diate guide 101 being provided between 'the paper and ribbon, all of these guides being provided with suitable apertures opposite the hammer. These rolls are journaled upon suitablebrackets attached to the frame of the machine in any suitable manner, the'roll 98 being journaled in sliding bearings inthe I frame 102 and being operated by thevfrictionroll 103, the two being held in contact by the tension of the springs`104. Motion is transmitted to the roll 103 through the medium of the rod 64, which has the pin 105, engaging in .the bell-crank lever 106, pivoted to the frame of the machine and carrying at its other end the pawl 107, engaging in the ratchetwheel 108 upon the shaft 109, upon which is secured the wheel 103. As the bar 64 is lowy ered once after each operation of bar 44, it is vided at its outer end with a ratchet-wheel 111,and a pin 112 upon an arln extendingfrom the bar 64 engageswith the lever 113,

the top of the machine.

evident the paper will be moved to present a new surface for each number to-be recorded. Whenever said bar'44 is operated, the roll 94y is carried upon the shaft 110, which is propivoted at its other end to the hanger from -This lever carries I '.f the-pawl 114, lwhichengageswith a ratchetin proportion to the value of that key, as-

previously described, and carries the segmental plate 80, Fig. 5,- with it, bringing the igure 9 opposite the aperture in the guides. When-the key has traveled to this position, the pin 30 of the arm 28 passes over the end 0f the key-lever, which forms the arc of a circle concentricwith the shaft 5, as shown in Fig. 3. The spring 36 on the segmental gear will now hold the rock-shaft stationary at its adjusted position and likewise the plate 80 during the further downward movement of the key, which new strikesthe bar 12 and operates the key-actuatingflever 13, which Acarries with it thearm 92, attached to the le- -ver 89, carrying the hammer 91, which is thrown quickly against the paper and ribbon l opposite the number, and the imprint of that number is made upon the paper. To print the next number, the key first operated is re- Y turned to its unoperated position, `and by the tension of the spring 36 the rock-shaft 26 is also returned to normal position, where it is stopped by striking the pin 137, adjustably secured in the side of the frame. This niotion likewise returns the plate to its Anormal position, with thecipher opposite the aperture in the guides.

f 138 is a lever pivotally secured to the bracket 139, connected at its lower end to the sliding bar 8 and at its upper end to, a sliding ratchet-bar 115, which latter is supported in suitable guides 116 and has ratchet-teeth upon its upper surface, with which the spring-pawl 117 engages, said pawl being secured to the sliding sleeve 88. Beside and parallel with the movable ratchet 115 is a stationary ratchet-bar 140, (shown in cross-section in Fig. 5,) with which the spring-pawl 118 engages. The

bars 115 'and 140 and pawls 117 and 118 are substantially the same construction as the bars 38 and 40 and pawls 37 and 39 previously described. Upon the depression of the rst key the bar 8 is moved from right to left and with it the lever 138, carrying the ratchetbar from left to right a distance of onenotch,

sitipn by the pawl 118, engaging-with the stationary ratchet-bar. The pawl 117 will now be thrown into engagement with thesecond notch on the bar 115. The operated key being now raised, the spring 134 will move the vwhile the sleeve is held stationary in its pobar s to the right and the level- 138 and barn' will return to their normal position, carrying with them by means of the pau-'l117the sleeve 88 a distance of one notch to theleft. As `the sleeve 88 is moved it carries with it the upper end ofthe lever 83 and through the connections described moves the sleeve 81 and plate 80 horizontally a sufficient distance to bring the next print of the type beside the.

first one. The operation of the second key will move the sleeve 88 and plate 80 another space to the left, and so on as each key is operated, thus bringing each succeeding print in its proper relative position, so that they will read in regular order-that is, the first one will represent units, the second one tens, and the third one hundreds, die. Now in case one of vthese iguresshould be a cipher it will be observed that the cipher upon the plate 8O is IOO IIO

always normally opposite the apertures v sition after a number is recorded completen A the following manner: The operator pulls out the setting-bar. 44, when the inclined lug 122 raises the bar 123, which at its upper end normally projects beneath the pawls 117 and 118 and lifting them allows the spring 124. to reof thepins.

turn the sleeve 88 to its initial position, carrying with it, through the medium of the lever 83, the sleeve 81 and plate 80.

My signaling apparatus consists of a series of bells or musical tines, such as 119, each bell or'tine representing a different note and designed to be rung at the operation of a key, the tone or pitch indicating the denomination of the operated tablet and registering-wheel. These tines are secured over the arm 20, and as said arm rises, as previously described, a latch 120, arranged on the upper side of the arm 20, engaging with the tine, passes above it, thereby causing it to vibrate and give forth a tone of the pitch desired. these tines for each group of ,tablet-rods or each registering-wheel, giving them, preferably, a rising pitch or a falling pitch, so that y the proprietor of the store without seeingthe engages thereunder.

My registering mechanism is of the following construction: Sleeved upon the shaft are the registering-Wheels 34, which are of the following construction: h is the wheelbody, which has formed upon its periphery a series of equidistant teeth t', being arranged upon one edge, as plainly shown in Fig. 12,

and upon the other edge the lateral annular projection j, forming between said flange and the shaft an annular groove la, in which are secured a series of pins Z, corresponding to the teeth 1', there being ten each of the teeth and These wheels are provided interiorly with a series of notches m, the intervening sectionsn forming the bearing upon the shaft. These wheels when journaled side by side, as shown in Fig. 11, are arranged with the'pins Z in proximity to the face of the adjoining wheel, and each is provided upon its circumference with suitable characters or figures representing the digits and a cipher. The rotation of one wheel a complete revolution turns its next adjoining wheel one notchwthat is, vrotates it one-tenth of a revolution-in' the manner hereinafter described. Each is held normally in its adjusted position by the spring-pawl 124, carrying a roller 125, adapted to engage in the notches between the teeth t'. The tension of the spring, with the roller, acting upon -the inclined sides of the teeth, acts to bring the wheels fully and accurately to theiradj usted position when moving from one notch to the next.

o is a latch or carrying device moving in the space formed between each pair of adjacent wheels. This latch extends outside beside one of the teeth t' and having the two lateral arms p q, the former extending within the I provide one of groove k of the adjoining wheel and the latter outside of the wheel.

s are a series of arms arranged in the path of the arms q, all so arranged that at some point of rotation the latch oof any Wheel will strike the arm s and cause the latch to project into the path of the pins Z of the adjoining wheel, carrying it one notch, when having passed by the arm s the spring r carries the latch out of engagement.

126 is a sliding bar moving in a keyway in the shaft 35 and having ahooked end 127,en gaging in the annular groove 128 upon the sliding sleeve 88, Figs. l, 4, and 11. This bar has a keyor stud 129, which in the initial position of the register engages in one of the grooves'or notches m inthe units-wheel. The connection between the gear-wheel33 and the shaft upon which the registering-Wheels are journaled is made through the 'spring-pawl 130, engaging with the ratchet-Wheel 131, firmly secured upon the shaft 35, said pawl moving wheel 131 in one direction only.

The parts being thus constructed, they are operated asfollows: Upon the depression of a key the rock-shaft 26 is rotated proportionately to the value of that key, as previously explained, through the series of graduated rock-arms 28. The motion of this shaft also moves the segmental gear 31 a proportionate amount, which in turn communicates m0- tion through thev pawl 130 and ratchet-wheel 131 to the shaft 35. Motion from this Shaft to the registering wheel is communicated through the studV or key 129 upon the sliding bar 126. At the operation of the first key this stud engages with the units-wheel, and the value of that key-say, for instance, the 3 key-is indicated through the slotted plate 132,01',inotherwords,the units-wheel isturned threenotches. While this is being done the key has traveled down the incline 10 upon the arm 9 and has reached the vertical portion 11. Simultaneously the pin 30 has traveled along the top of the key until it' has reached the end thereof, when it passes downI across the segmental circularbearing 133, during which period the shaft 26 is held stationary. The rotationof this shaft carries with it the cams 25, against which bears the hanger 23, held in contact therewith by the spring 27. These cams are of such shape that the hanger 23 is carried backward by the spring 27 toward the tablet-rods through a distance proportionate'to the amount of rotation of said shaft and by the connections described carries with it the upwardly projecting arm e. If a 5 key were struck, the rotation of the cam would be sufficient to carry the arm e under the 5 tablet-rod in the group of tablet-rods, and if the key 9 were struck the movement of the arm e would be sufficient to carry it under the 9 tablet. The ci pher-key is not connected to the shaft 26 and theL arm e is Vnormall y underthe ci pher-tablet. As soon as the key enters upon the vertical portion 11 of the IIO arm 9 lit strikes the cross-bar 12, depressing f the tablet-operating lever 13,which raises the movable tablet-arm 2O with the lifting-arm e and raises the tablet-rod above it which has .Y been previously depressed, and with it its tab- '.let-,until the pawl 60 engages under the shoul-y .der 59 and holds said tablet-rod in itselevatedf Yposition. The travel of the key downward` upon the incline carries the bar 8 to the left against the tension of the spring 134 and carrieswith it the lever138, connected to the slid-` ing ratchet 115. The rotation of the shaft 26 turns, also, the ligure-plate S0, so that the uum-v ber corresponding to the key struck is oppositev the apertures in the guides, and the hammer', being connected to the lever 13, as previously described, strikes against the paper and ribbon vopposite Athat number, thus printing it upon the paper. -The rotation of the' shaft also rocks the segmental gear 31 proportionate to the value of the key struck, which transmits a corresponding motion to the shaft through the sliding connection 129 to' the units-wheel of the registering mechanism. As the lever 13 rises, it carries with it the bar 64,.which through the hood and connection described covers from the obser` vation of the customer lthe elevated tablet-rod, the bar 64 being held in its adjusted position by the spring 78.v The elevation of the lever 13 carries with it also the arm'20, as

previously described` which through the spring-latch 120 strikes Vthe alarm .or tine`11'9' of a pitch to indicate to the proprietor, if he be at` hand',` that an amount in units has been struck. Ast-heop'erator releases his hold the v keyis'withdrawn to its initial position by the I l 'sp-ring 36 withdraws the seglnental gear 3l to of tablet-rods.

its normal position without actuating the registering mechanism, as the spring-pawl 130 returns over the ratchet-wheel 131 without operating the same. The bar 8 is'retu'rned to the right by the tension of the spring 134 Y and carries with it the lower end of the lever 138,-which' moves to the lef t'the sliding rack- 'bar 115, which through. the connection of they pawl 117, connected to the sleeve SS, carries said sleeve, and with it the sliding bar 126, having the lug 129, which is moved to connection with one of thel notches lm, Figs. 12 and 13, in the registeringwvheel of the next higher denomination. The movement to the rightv of the bar 8 and ratchet 38 through the pawl engaging therewith carries, also,v the sleeve 18, and with it the tablet-operating arm 20, one notch to the right, so that the arm e' extendsv beneath the next or tens7 group The motion of'the sleeve S8 communicates motion through the medium of the lever 83, the pin 85, engaging in a slot 86 in the sleeve S1 to the ligure-plate 80, carrying it to the left a sufficient distance, so that the next blow ot the hammer will print a iigure upon the paper in proper relation thereto to be read consecutively. With the parts .adjusted in this position the operator again depresses a keyof any desired denomina tion, and,.the parts operating as previously f described', a tablet-rod of the second denomination will be actuated in the tens group, a registering -wheel of the second denomination will .be operated, the 'ligure will be `recorded upon the paper in the place of f the second denomination, and all .the parts upon the release of the keywill be moved foryward to connect with the next higher dev nomination. In thiscondit-ionof the machine.

hood, allowing the customer tosee theamount indicated bythe tablets. At the same time, through the medium of the levers and pawls described and connecting withv the frictionl' roll 103 and the ribbon-roll *94,v each of these l will be turned upon its'axis one notch of the ratchet, bringing a new place upon the paper f and the ribbon opposite the aperture in the guides for the next record. In order to register, indicate, and record a'second number,

IOO

.the parts which yhave been adjusted forward to the highest denomination of the last num? ber operated must be returned to theirinitial position, and to do this the operator must withdraw the bar 44.: In doing this the inclined lug 43 will raise the lifting-bar 41, disengaging ythe pawls 37 and 39 from the ratchet,

f when the spring 141 (shown in hig.-7)v returns the arm 2O to its initial position. This saine I'Io motionof the bar 44 causes the lifting-bar amount is desired to b e'indicated,registered,v

and recorded. Upon the operation of the key i with the parts in this position the tablet-aot- Yuating lever 13strikes the arm 79 of the bar 64 and causes the latch 65 to passup the ineline 66, carrying the bar to the right,`

and with it all of the spring-pawls 60, disenygaging said pawls from the shoulders upon the tabletqods, allowing all the operated rods to drop. As soon as the latch 65 has passed above the incline 66, the tension ofthe springs upon the pawls 60 will throw the bar 135 back to its initial position, in which position the pawls will be free to engage under the shoulder 59 of any operated tablet-rod, as previously described.

My locking mechanism for preventingrthe simultaneous operation of two keys upon the tablet mechanism allows the registering of the highest of those two numbers without registering the other, but prevents' the operator from effecting the indication of any amount, so that when he comes to expose to the pur- Chaser by raising the hood the amount of his purchase 4the purchaser will see that nothing is indicated whatever, or if he should release one key and continue the operation of the other that an improper amount is indicated.

The hood obscures theindicat-ing-tablets until the operator pushes in the resetting-bar 4:4, which depresses the bar 64 and brings it in such relation to the tablet-actuating lever, as shown in Fig. 9, that the operator cannot indicate any other amount additional to what has been already done without throwing down all of the operated tablets, and at the same time raising the bar G4 and obscur-ing from the view of the purchaser the amount indicated. i

The repeated operation of a keyvactuating only the tablet mechanism is prevented by the fact that such repeated operation will be indicated upon the recording mechanism, thereby indicating that certain amounts have not been registered, but have been indicated and improperly recorded.
